Collagenase injection softened extracellular matrix stiffness and altered Hippo signaling by increasing the transcriptionally inactive form of YAP (phospho-YAP).• Verteporfin and nintedanib inactivated YAP and reduced transcription of genes involved in fibroid cell growth and fibrosis.• The results suggest a possible role of Hippo/YAP signaling as a therapeutic target for fibroid treatment.
